Description

Technical Field

[0001] The invention relates to the field of medical sampling, and more particularly to a renal hemodialysis sampling device. Background Art

[0002] Renal hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers to remove metabolic waste from the body, maintain electrolyte and acid-base balance; at the same time, it removes excess water from the body and returns the purified blood to the body.

[0003] Renal hemodialysis sampling refers to the process of collecting blood samples from patients during or before and after hemodialysis. During the collection process, when medical staff pull the piston handle hard, the piston shaft is prone to deviation and shaking, resulting in poor stability and smoothness of the piston shaft during movement.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, a Chinese patent with authorization announcement number CN115177250A discloses a hemodialysis sampler for nephrology. When the device is used, the piston shaft and the piston fixed at the bottom end of the piston shaft are driven by the piston handle to move toward the top end of the syringe. The slide rod slides in the guide sleeve to limit and guide the piston shaft. A negative pressure chamber is formed between the piston and the bottom of the inner cavity of the syringe. The blood flows through the needle and the nipple of the syringe in turn into the negative pressure chamber in the syringe to complete the sampling. The above solution is adopted to achieve the limiting and guiding effect of the piston shaft through the cooperation of the slide rod and the guide sleeve, thereby improving the stability and smoothness of the piston shaft during movement.

[0005] However, in actual production operations, the above-mentioned device still has some problems. For example, when using a syringe to collect dialysate samples, although the syringe is a disposable syringe, it is easily contaminated by external bacteria after the package is torn open. At the same time, after using a syringe to collect samples of renal hemodialysis, the sample is at room temperature, which is prone to temperature fluctuations and bacterial contamination, which will accelerate the changes in the sample and reduce the accuracy of the test results.

[0020] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0021] In the above scheme, the needle of the disposable syringe to be sampled is placed in the disinfection port, and the needle is completely immersed in the alcohol disinfectant in the alcohol box. After immersion, the disposable syringe is taken out. Through immersion, it can be ensured that all parts of the needle are fully in contact with the alcohol, thereby achieving a comprehensive disinfection effect. At the same time, during the immersion process, the concentration of alcohol can be maintained at a high level, thereby ensuring a better disinfection effect.

[0022] The motor body is used to start the driving fan to rotate along the inner side of the fixed side cylinder to generate wind force, and the wind force will blow toward the inner side of the volatilization groove along the air guide port. The continuously generated wind force can be blown toward the needle part at the bottom of the storage groove, thereby accelerating the volatilization of the alcohol liquid on the surface of the syringe, reducing the reaction between the residual alcohol disinfection liquid and the dialysate, and improving the effect of subsequent extraction of the dialysate.

[0023] Both ends of the fixed side cylinder are protected by a dust-proof net, which can reduce the dust and other particles from being blown onto the surface of the disposable syringe by wind. At the same time, the top transmission rod will drive the transmission vertical plate to rotate during the rotation process. The rotating transmission vertical plate can drive the cleaning brush to rotate along the surface of the dust-proof net for cleaning, which can reduce the adhesion of dust and other particles on the surface of the dust-proof net and improve the use effect.

[0024] Through the connection of cables, the battery is used to drive the disinfection lamp through the transmission of the cable. After the disinfection lamp is started, it will irradiate the disposable syringe inside the volatilization tank. The disposable syringe can be disinfected when it evaporates, thereby improving the sterility of the disposable syringe and reducing the impact of bacterial attachment on subsequent sampling.

[0025] After the water pump body is started, the water pump body can be used to drive the liquid lifting pipe to transport the liquid in the insulation drawer to the liquid outlet pipe on one side of the water pump box, and the liquid is discharged downward through the liquid outlet pipe to the surface of the water-absorbing fiber evaporator in the square frame. The water-absorbing fiber evaporator can quickly reduce the temperature in the sample box, thereby improving the effect of placing the sample in the sample box.

[0026] The exhaust fan is driven to rotate by the motor body. After the rotating exhaust fan generates wind along the protective side panel, it will blow the cooled air on one side of the water-absorbing fiber evaporator to the surface of the sample test tube, thereby improving the cooling effect of the sample test tube, helping to maintain the stability of the sample and preventing the sample from deteriorating or the destruction of blood cells during transportation.

[0027] The cold air generated by the exhaust fan blows along the guide sleeve to the surface of the heat-conducting metal plate, thereby cooling the surface of the heat-conducting metal plate. Therefore, the disinfecting alcohol in the alcohol box can be cooled simultaneously when the exhaust fan generates cold air for cooling. The situation in which the concentration is reduced due to accelerated evaporation of alcohol due to excessive temperature can be reduced. By maintaining the stability of the alcohol concentration, the effect of alcohol on needle disinfection can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Before pulling the insulation drawer 808, the medical staff will drive the limit L frame 904 to move downward by pressing the pressing plate 905. The downward moving limit L frame 904 will drive the limit spring 903 to form a compression deformation along the inner side of the side fixing box 901. After moving downward, the limit L frame 904 will be separated from one side of the insulation drawer 808. At this time, the insulation drawer 808 can be pulled open along one side of the sample box 1. After pushing the insulation drawer 808 back, the limit spring 903 loses its limit position, which will drive the limit L frame 904 to move upward. After the limit L frame 904 moves upward, one side of the limit L frame 904 will fit with one side of the insulation drawer 808. At this time, the limit L frame 904 can be used to limit the insulation drawer 808 to reduce the possibility of the insulation drawer 808 being opened during the transportation of the sample box 1.

After the liquid passes through the surface of the water-absorbing fiber evaporator 1003, the moisture will be absorbed by the fiber material. With the action of heat, the moisture begins to evaporate, thereby absorbing the surrounding heat, thereby quickly reducing the temperature in the sample box 1, and the excess liquid will flow back to the insulation drawer 808 along the drainage pipe 1009 at the bottom of the bottom drainage box 1001. The temperature in the sample box 1 can be quickly reduced through the water-absorbing fiber evaporator 1003, thereby improving the effect of placing the sample in the sample box 1.

The synchronous rotation of the bottom transmission gear disk 1106 will drive the side transmission rod 1107 to rotate. When the side transmission rod 1107 rotates, it will drive the exhaust fan 1108 to rotate. After the rotating exhaust fan 1108 generates wind along the protective side plate 1113, it will blow the cooled air on one side of the water-absorbing fiber evaporator 1003 to the surface of the sample tube 806, thereby improving the cooling effect of the sample tube 806, helping to maintain the stability of the sample and preventing the sample from deteriorating or the destruction of blood cells during transportation.

[0078] At the same time, when the disposable syringe is volatilizing the residual liquid of alcohol disinfectant on the surface of the storage groove 704, the cable 7021 is connected and the battery 7022 is used to drive the disinfection lamp 7020 through the transmission of the cable 7021. The disinfection lamp 7020 is fixed to the inner side of the square side groove 7018 through the side lamp holder 7019. After the disinfection lamp 7020 is started, it irradiates the disposable syringe on the inner side of the volatilization groove 705. The disposable syringe can be disinfected when it evaporates, thereby improving the sterility of the disposable syringe and reducing the impact of bacterial attachment on subsequent sampling.

[0079] An inner limit frame 7013 is fixedly connected to the inner side of the fixed side tube 707 , a side of the inner limit frame 7013 is movably connected to a bearing plate 7014 , and one side of the bearing plate 7014 is movably connected to one side of the side connecting plate 709 .

[0081] Both sides of the fixed side tube 707 are fixedly connected with an outer connecting ring 7015, the inner side of the outer connecting ring 7015 is fixedly connected with an inner connecting ring 7016, and the inner side of the outer connecting ring 7015 is movably connected with a dustproof net 7017.

[0082] When the transmission fan 7010 generates wind, both ends of the fixed side cylinder 707 are protected by the dust-proof net 7017, which can reduce the dust and other particles from being blown to the surface of the disposable syringe by the wind. At the same time, the top transmission rod 708 will drive the transmission vertical plate 7011 to rotate during the rotation process. The rotating transmission vertical plate 7011 can drive the cleaning brush 7012 to rotate and clean along the surface of the dust-proof net 7017, which can reduce the adhesion of dust and other particles on the surface of the dust-proof net 7017 and improve the use effect.

[0083] The working process provided by the present invention is as follows:

[0084] When the present invention is used, firstly, the needle of the disposable syringe to be sampled is placed in the disinfection port 604, and the needle is completely immersed in the alcohol disinfectant in the alcohol box 601. After immersion, the disposable syringe is taken out. By immersion, it can be ensured that all parts of the needle are fully in contact with the alcohol, thereby achieving a comprehensive disinfection effect. At the same time, during the immersion process, the concentration of alcohol can be maintained at a high level, thereby ensuring a better disinfection effect.

[0085] After the disposable syringe is disinfected, it is placed on the surface of the storage tank 704 so that the needle is suspended inside the volatilization tank 705. The motor body 702 is started to drive the transmission fan 7010 to rotate along the inside of the fixed side cylinder 707 to generate wind force. The wind force will blow toward the inside of the volatilization tank 705 along the air guide port 706. The continuously generated wind force can be blown toward the needle part at the bottom of the storage tank 704, thereby accelerating the volatilization of the alcohol liquid on the surface of the syringe, reducing the reaction between the residual alcohol disinfection liquid and the dialysate, and improving the effect of subsequent dialysate extraction.

[0086] At the same time, when the transmission fan 7010 generates wind, both ends of the fixed side cylinder 707 are protected by the dust-proof net 7017, which can reduce the dust and other particles from being blown to the surface of the disposable syringe by the wind. At the same time, the top transmission rod 708 will drive the transmission vertical plate 7011 to rotate during the rotation process. The rotating transmission vertical plate 7011 can drive the cleaning brush 7012 to rotate and clean along the surface of the dust-proof net 7017, which can reduce the adhesion of dust and other particles on the surface of the dust-proof net 7017, thereby improving the use effect.

[0087] When the disposable syringe volatilizes the residual liquid of the alcohol disinfectant on the surface of the storage groove 704, the battery 7022 is connected through the cable 7021 to drive the disinfection lamp 7020 to work through the transmission of the cable 7021. After the disinfection lamp 7020 is started, it irradiates the disposable syringe inside the volatilization groove 705, and the disposable syringe can be disinfected when it evaporates, thereby improving the sterility of the disposable syringe and reducing the influence of bacterial attachment on subsequent sampling.

[0088] When sampling, first tilt the dialyzer about 45 degrees, with the dialysate outlet facing downward, remove the dialysate quick connector at the arterial end of the dialyzer, and watch the dialysate flow out of the dialyzer for 5 seconds. Use a sterile syringe to draw 3-5 mL of dialysate, and then inject the dialysate into the sample tube 806;

[0089] The materials of the sample box 1 and the insulation drawer 808 are both insulation materials. The temperature in the sample box 1 can be lowered by ice cubes and liquid in the insulation drawer 808. After obtaining the sample, the side guard plate 803 is taken out along one side of the side clamping frame 801, and after opening one side of the sample box 1, the sample test tube 806 is placed inside the test tube rack 804, which can improve the stability of the sample during transportation and improve the effect of the sample;

[0090] After the water pump body 1007 is started, the water pump body 1007 can be used to drive the liquid extraction pipe 1005 to transport the liquid in the heat preservation drawer 808 to the liquid outlet pipe 1008 on one side of the water pump box 1006, and the liquid is discharged downward to the surface of the water-absorbing fiber evaporator 1003 in the square frame 1002 through the liquid outlet pipe 1008. The temperature in the sample box 1 can be quickly reduced by the water-absorbing fiber evaporator 1003, thereby improving the effect of placing the sample in the sample box 1;

[0091] At the same time, the exhaust fan 1108 is driven to rotate by the motor body 702. After the rotating exhaust fan 1108 generates wind along the protective side plate 1113, it will blow the cooled air on one side of the water-absorbing fiber evaporator 1003 toward the surface of the sample tube 806, thereby improving the cooling effect of the sample tube 806, helping to maintain the stability of the sample and preventing the sample from deteriorating or the destruction of blood cells during transportation.

[0092] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.

[0093] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
